Drive 4 worked. With focus detected and the detector validated live against a known transition (NEW GAME, down, LOAD GAME -- CONTROL PASSED), the drive navigated and pressed through, and every step confirms against a committed capture: main menu +0.999, newgame-difficulty +0.999, newgame-selectdata-crash +0.997. Then the guest throws, PC 0x82307128 times 349, and no S00A voice stream ever decodes. It is on the new-game path rather than the boot: the log order is ADV attract, then BGM_103 menu music, then the throw. So it is not the ~100 s boot throw that title-crash-stl-tree.md documents. That page attributes the throw to an incomplete on-disc cache and Q4 s note cites it for this crash. The attribution survives, but not through the container the page names. aab216c3 is complete here at 7 files. The line immediately before the exception resolves \1b556564\9\00c8dcd, and 1b556564 holds exactly one file plus a stray 1b556564900c8dcd.tmp -- precisely the page s run C, partially rebuilt, which throws. So the new-game path builds a different cache container from the title path and that one is incomplete. The page s remedy does not transfer. It restores a previously complete cache, and no complete 1b556564 has ever existed here: the game crashes while building it, leaving the .tmp, so the cache cannot complete and re-running does not escape it. Its own run B shows a fully cold cache throws as well, so deleting does not help. Consequence recorded: the centre-channel voice result stays resting on ADV alone, because the corroborating asset is behind a crash that is outside menu-port scope.

Sylpheed
A clean-room reverse engineering and port project for Project Sylpheed: Arc of Deception (Xbox 360, 2007).
Three things live here, in one repository so that a change spanning them lands as one commit:
| The decoders | crates/sylpheed-formats — the disc's formats, read and verified disc-wide |
| The port | port/ — a Godot 4 project, plus crates/sylpheed-export which converts a disc into the open asset tree it reads |
| The corpus | docs/re/ — what has been reverse engineered, with its evidence, its retractions and its dead ends |
You need your own copy of the game. No game content is in this repository and none ever will be. The exporter reads the disc you supply.
The oracle is the real game
sylpheed-cliand the Explorer are tools for verifying our decoding. They are hypotheses under test and they have been wrong. When something must be checked against the truth, the truth is the game running in Xenia Canary, captured — not any renderer of ours.
This is stated first because getting it backwards is the most expensive mistake this project has made.
Layout
crates/
sylpheed-formats/ the decoders. Disc-wide verified; the corpus is its spec
sylpheed-cli/ headless tools -- render a screen, dump a table, probe audio
sylpheed-viewer/ the Explorer: a human's window onto the disc. STATIC data only
sylpheed-export/ disc -> the open, moddable asset tree
port/ the Godot 4 project. Reads open formats ONLY
authored/ decisions that are NOT on the disc, each with its reason
data/
base/ generated by the exporter. Gitignored, never hand-edited
mods/ drop-in overrides. Yours
docs/
re/ the corpus: findings, refutations, method traps
game/ how the game is navigated -- menus, modals, flight
port/ the port's mission, its handoff contract, modding rules
agents/ how the agent team works together

Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.

Confidence is per claim, never per document: ✅ CONFIRMED · 🟡 PROBABLE ·

rather than deleted — that is why the numbers here can be trusted.
